chi::driver::rawmemory
CHI::Driver::RawMemory(3pm) User Contributed Perl Documentation CHI::Driver::RawMemory(3pm)NAME
CHI::Driver::RawMemory - In-process memory cache that stores direct references
VERSION
version 0.54
SYNOPSIS
use CHI;
my $hash = {};
my $cache = CHI->new( driver => 'RawMemory', datastore => $hash );
my $cache = CHI->new( driver => 'RawMemory', global => 1 );
DESCRIPTION
This is a subclass of CHI::Driver::Memory that stores references to data structures directly instead of serializing / deserializing. This
makes the cache faster at getting and setting complex data structures, but unlike most drivers, modifications to the original data
structure will affect the data structure stored in the cache, and vica versa. e.g.
my $cache = CHI->new( driver => 'Memory', global => 1 );
my $lst = ['foo'];
$cache->set('key' => $lst); # serializes $lst before storing
$cache->get('key'); # returns ['foo']
$lst->[0] = 'bar';
$cache->get('key'); # returns ['foo']
my $cache = CHI->new( driver => 'RawMemory', global => 1 );
my $lst = ['foo'];
$cache->set('key' => $lst); # stores $lst directly
$cache->get('key'); # returns ['foo']
$lst->[0] = 'bar';
$cache->get('key'); # returns ['bar']!
CONSTRUCTOR OPTIONS
Same as CHI::Driver::Memory.
SIZE AWARENESS
For the purpose of size-awareness, all items count as size 1 for this driver. (Because data structures are not serialized, there's no good
way to determine their size.)
# Keep a maximum of 10 items in cache
#
my $cache = CHI->new( driver => 'RawMemory', datastore => {}, max_size => 10 );
ACKNOWLEDGEMENTS
Thanks to Yuval Kogman whose Cache::Ref inspired me to do this.
